The ALMA astronomical observatory took another step forward and upward, as one of its state-of-the-art antennas was carried for the first time to Chile’s 16,500-foot-high plateau of Chajnantor on the back of a giant, custom-built transporter.

A West Virginia high-school student analyzing data from a giant radio telescope has discovered a new astronomical object — a strange type of neutron star called a rotating radio transient.

Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun’s gravity, and their technique promises a major contribution to a frontier area of basic physics.

Using a worldwide combination of diverse telescopes, astronomers have discovered that a giant galaxy’s bursts of very high energy gamma rays are coming from a region very close to the supermassive black hole at its core. The discovery provides important new information about the mysterious workings of the powerful engines in the centers of innumerable galaxies throughout the Universe.

Radio astronomers have directly measured the distance to a faraway galaxy, providing a valuable yardstick for calibrating large astronomical distances and demonstrating a vital method that could help determine the elusive nature of the mysterious Dark Energy that pervades the Universe.

Astronomers have discovered a unique double-star system that represents a missing link stage in what they believe is the birth process of the most rapidly-spinning stars in the Universe — millisecond pulsars.
